| Abstract Scope |
Military interests include in-situ on-aircraft repair, which can be completed through robotic friction stir additive manufacturing (R-FSAM) techniques. Using a robot enables a deployable system that can be sent to the point-of-need and offers enhanced flexibility, due to additional degrees of freedom compared to a traditional mill, allowing for repairs to be completed without removing aircraft panels. Current R-FSAM methods involve feeding wire to reduce the axial forces required for deposition. However, traditional FSAM utilizes bar feedstocks, which require higher forces for deposition, but has much faster deposition rates. This work investigates utilizing friction surfacing to deposit low-diameter (<½") bar stock onto a substrate using an independently controlled spindle motor. An ABB IRB 120 is controlled by force/position for the surface deposition, while the spindle is controlled for the bar stock’s rotation speed. The R-FSAM friction surfacing results are compared to repairs made using a conventional knee mill. |
